星系团观测对复合Dirac中微子的约束

Constraints on composite Dirac neutrinos from observations of galaxy clusters

R. S. Hundi, Sourov Roy

摘要:

最近,为了解释中微子质量的起源,人们提出了一个基于右手手征中微子中隐藏的费米子束缚态的模型。在这个模型中,压缩隐藏扇形场的结果之一是存在keV质量的无菌复合狄拉克中微子,它可以形成可行的温暖暗物质粒子。我们分析了这个模型的约束条件,从卫星望远镜的观测,以检测星系团中的不育中微子。

英文摘要:

Recently, to explain the origin of neutrino masses a model based on confining some hidden fermionic bound states into right-handed chiral neutrinos has been proposed. One of the consequences of condensing the hidden sector fields in this model is the presence of sterile composite Dirac neutrinos of keV mass, which can form viable warm dark matter particles. We have analyzed constraints on this model from the observations of satellite based telescopes to detect the sterile neutrinos in clusters of galaxies.
